Take your marble run to a new level with the Techno Gears Marble Mania Galaxy kit by the Learning Journey! This building kit will allow your child to blast off into engineering fun. This space-themed 425 pieces marble run includes many new features that will take your kids over the moon. Some new planetary additions include pictures of planets hanging off the run so your marbles really do move through the solar system, a rocket in the middle so your child's constructions can lift off, and a lot of new pieces! There are spirals, a steep slide, a better construction system that contains pieces that hold up the run better, and an automatic launcher that will send your marbles into orbit. The Techno Gears Marble Mania Galaxy from Educational Toys Planet also features some fun electronic effects such as pace sounds, blinking lights, and even some glow-in-the dark components! Colors may vary. This space-themed marble run set requires 3 AA batteries.
